In previous phase 2 studies, pemetrexed has shown antitumor activity in advanced non-small cell lung cancer as a single agent as well as in combination with cisplatin. Since the introduction of vitamin supplementation, pemetrexed has shown good tolerance and high safety. Vitamin supplementation has opened the opportunity to offer patients higher pemetrexed dosing, as has been demonstrated by a recent Phase 1 study. The higher dose with supplementation may increase pemetrexed's efficacy without unduly compromising safety. The present Phase 2 study will use pemetrexed dosing that is tailored to individual patient tolerance, and is an effort to determine the efficacy and safety of this approach in patients with advanced NSCLC who had prior chemotherapy.

To characterize the quantitative and qualitative toxicity of pemetrexed when used at tailored dosing in this patient population
